Once we get to 1st February 2023 will we still be able to do the following:

a - open the company file and run various reports and export data?

b - enter transactions?

c - Submit MTD VAT returns?

Can you please advise what the situation will be be both a pro-advisor licence and for our clients normal licences? 

Will it be just the support that ends at that point (i.e. no telephone support and no software updates/patches) or will any of the above list also no longer work?

The short 15 month notice is not enough to migrate clients to another product, especially with QBO still falling way short of what QuickBooks desktop can do even for basic clients.
